FIELD OF THE INVENTION
[0001] The present invention relates to a chemicals kit prepared for the processing of photographic
light-sensitive materials and a processing method which uses the chemicals kit; particularly
to improvement of the preservability of a processing chemicals kit by way of preventing
the package materials used therefor from degrading; and more particularly to techniques
to produce a kit which, even when used after its long preservation, can provide satisfactory
photographic characteristics, and which is packed in a compact disposable packaging
material whose combustion calorie at the time of its incineration after disposal is
as low as not to harm the environment.
BACKGROUND OF THE INVENTION
[0002] A color photographic light-sensitive material for camera use, after being imagewise
exposed, is usually subjected to processing steps comprising color developing, bleaching,
fixing, washing and/or stabilizing; a color photographic paper, after being exposed
in a printing process, is subjected to processing steps comprising color developing,
bleach-fixing (bleaching, fixing), washing and/or stabilizing; and a black-and-white
light-sensitive material, after being exposed, is usually subjected to developing,
fixing and washing. Further, in the case of a reversal-type light-sensitive material,
a reversal processing step is added to these processing steps.
[0003] The processing solutions used for these processing steps are commercially available
in the kit form of concentrated solutions from the ease of transport/handling point
of view.
[0004] As the packaging material for these concentrated solutions there have conventionally
been used plastic bottles, glass bottles and aluminum-sandwiched film containers.
The glass bottle, however, if handled roughly during its transport process, tends
to be broken to cause its content to run out. The plastic bottle, when dropped into
the discard, is not easily collapsible, so bulky to take up much room in a dumping
ground, and, when destroyed by fire, emits as extremely high a combustion calorie
as to damage the incinerator. In addition, the incineration creates a vast amount
of carbon dioxide, which is considered a cause of the latest global warming issue.
What is more important is that the plastic bottle, when burried under the ground,
does not decompose semipermanently, resulting in the problem that the reclaimed ground
cannot be solidified. The film container made of aluminum (as a gas barrier) sandwiched
by polyethylene resin sheets has also various shortcomings; for example, when subjected
to incineration treatment, the container is reduced to ashes, leaving the aluminum
as an incinerated residuum, whose secondary treatment remains as a problem yet to
be solved. Further, the ash causes such a trouble as the incinerator's filter clogging
at the time of incineration.
[0005] Besides, when the aluminum-sandwiched film container is used for the storage of low-pH
concentrated kit solutions, its aluminum section tends to corrode or to cause delamination,
while when used for the storage of a strongly oxidizing bleacher such as ferric 1,3-propylenediaminetetraacetate,
the above problem becomes more conspicuous.
[0006] Further, as packaging materials similar to that of the invention there have conventionally
been known large packaging materials of 5-liter to 20-liter capacities such as those
described in JP E.P. No. 14209/1929, Ekitight (trade name), produced by Dai Nippon
Printing Co., Lontainer N (trade name), produced by Sekisui Seikei Kogyo Co., which
are partly used for photographic chemicals. These packaging materials each are one
consisting of two or three outer and inner bags. It is difficult to produce such bags
because their manufacture not only is costly with a heavy burden imposed thereon but
also has the problem that their joined portions tend to become broken at the time
of undergoing oscillation. When a concentrated solution containing a bleaching agent
or antioxidation agent is stored over a long period of time in the above-mentioned
bag, the joined portions of the bag tend to deteriorate the quality of the content
with time.
[0007] In recent years, as the number of small-scale photofinishers called 'minilabs' increases,
the amount of consumption of processing chemicals for small-sized automatic processors
increases. Under the above conditions the number of processing chemicals packaging
materials thrown into the discard naturally increases as well. Thus, the above fact
has become an important issue.
[0008] As another problem, there are cases in which the above concentrated kit solution
is stored over an extremely extended period of time, encounters a high temperature
exceeding 50°C, or undergoes oscillation; these situations deteriorate the quality
of its content, which, when actually used, is unable to provide objective photographic
processing characteristics. Not only that, the deteriorated processing chemicals,
when used in an automatic processor, bring about the problem that they tend to deposit
on the inside walls of the processor. For this reason, there are demands for the development
of a new packaging material capable of retaining the intrinsic characteristics of
its content, photographic processing chemicals, under any severe conditions.
SUMMARY OF THE INVENTION
[0009] It is an object of the present invention to provide a photographic processing chemicals
packaging material capable of protecting the photographic processing characteristics
of its content against any storage conditions accompanied by a high temperature or
oscillation.
[0010] It is another object of the invention to provide a photographic processing chemicals
packaging material excellent in the aptitude to environmental conditions for the reason
that it is easily collapsible and disposable, emits as low a combustion calorie at
the time of its incineration as not to damage the incinerator, and produces little
carbon dioxide gas in the incineration.
[0011] It is a further object of the invention to provide a processing chemicals packaging
material in the form of a film container improved to be free from corrosion and delamination.
[0012] It is still another object of the invention to provide a processing chemicals packaging
material improved to little cause its content to deposit on the inside walls of an
auto-processor.
[0013] It is a still further object of the invention to provide improvement of the preservability
of the processing chemicals kit.
[0014] Other objects of the invention will become apparent from the following descriptions.
[0015] The above objects of the invention can be accomplished by any one of the following

[0016] Improvement on the preservability of the processing chemicals kit for the silver
halide photographic light-sensitive material of the invention can be accomplished
by the following constructions, along with the above photographic processing chemicals
packaging material.
(1) Where the silver halide photographic light-sensitive material processing chemical
is a bleacher, the bleacher contains at least one of those compounds represented by
the following Formula B:
Formula B X₂-A-COOM³
wherein X₂ represents a hydroxyl group, a halogen atom, an amino group or a -COOM³
group; A is a saturated or unsaturated alkylene group when may have a substituent;
and M³ is a hydrogen atom, an ammonium group, an alkali metallic atom or an organic
ammonium group. Further, the preferred embodiment of the invention is such that in
the above silver halide photographic light-sensitive material processing kit and a
processing method which uses the kit, the packaging material for the kit has a steam
transmittance of not more than 10 g/m².day, the packaging material is of a multilayer
structure, and the processing kit contains a processing solution having a bleaching
function.
(2) Where the silver halide photographic light-sensitive material processing chemical
is a color developer replenisher, the replenisher contains at least one of those compounds
represented by the following Formula 1:

wherein L represents an alkylene group which may have a substituent; A is a carboxyl

(3) Where the silver halide photographic light-sensitive material processing chemical
is a fixer, the ammonium ion inside the kit accounts for not more than 50 mol% of
the whole cations in the kit.
[0017] Incidentally, the term 'kit' herein is synonymous with the kit used by those skilled
in the art. For example, a kit for a color developing solution comprises a color developer
part, a preservative part and an alkali agent part. For preparation of a replenisher,
the three parts are dissolved in a given amount of water, and to the solution is then
added water to make the whole a prescribed amount (designated by a manufacturer).
A set of these chemicals parts is called a kit.
[0018] The 'flexible container' in the invention means a container which is formed with
a film having a thickness of not more than 500µm, preferably not more than 200µm and
which is easily collapsible when empty; for example, the container is composed of
independent bottom and body parts joined and, when full of its contents, is able to
stand alone, while, when empty, is easily collapsible, - the so-called standing pouch,
unlike monoblock-molded plastic containers popularly used by those in the art, having
a wall thickness of 1000 µm or more and uncollapsible even when empty.

DETAILED DESCRIPTION OF THE INVENTION
[0023] The resin used for the polyolefin resin layer is preferably a polyethylene, particularly
LLDPE (linear low density polyethylene), from the moisture permeability and strength
point of view. The thickness of the layer is preferably 30 to 500µm, and more preferably
50 to 300µm.
[0024] The preferably usable as the polyamide resin is nylon from the antipiercing strength
and antipinhole characteristic point of view. The thickness of it is preferably 3
to 50µm, and more preferably 5 to 30µm.
[0025] Particularly, drawn nylon is preferable for the object of the invention. The aforementioned
ceramic is an inorganic material composed principally of silicon oxide, which may
be used under vacuum for coating a polyethylele or polyethylene terephthalate film.
Particular examples of this include GL type ceramic-evaporated film, manufactured
by Toppan Printing Co., Ltd.
[0026] As the ethylene-vinyl alcohol copolymer resin there are Kuraray Eval Films EF-XL,
EF-F, EF-E, etc., manufactured by Kuraray Co., Ltd.
[0027] The halogen for the foregoing polyhalogenated vinylidene resin and polyhalogenated
vinyl resin includes chlorine, fluorine and bromine. Examples of the resins include
polyvinylidene chloride, polyvinyl chloride, polyvinylidene fluoride, polyvinyl fluoride,
and the like.
[0028] In the invention, however, for the reason that emission of a harmful gas at the time
of incineration is undesirable from the viewpoint of the protection of environment,
out of the foregoing group of resins the resins A to E are preferably used, and more
preferably the resins A to C.
[0029] As the resin for the invention, there may be used any common one of those as described
in the revised edition of the 'Plastic Film,' written by Gisaku Takahashi, published
by Nikkan Kogyo Shimbun Dec. 20, 1976.
[0030] The steam transmittance of the packaging material of the invention is preferably
not more than 20 g/m².day, more preferably not more than 10 g/m².day, and most preferably
not more than 5 g/m².day. While the correlation between the steam transmittance of
the packaging material and the change in quality of photographic processing chemicals
has so far been unknown, it has been found that the effect of the invention can become
significant by controlling the steam transmittance to a specific value. Measurement
of the steam transmittance was made in the usual manner according to JIS Z 0208.
[0031] The oxygen transmittance of the packaging material of the invention is preferably
not more than 10 ml/m².day.atm, more preferably not more than 5 ml/m².day.atm, and
most preferably not more than 3 ml/m².day.atm. The oxygen transmittance was measured
in the usual manner according to JIS Z 1707.
[0032] The thickness of the film as the packaging material of the invention is preferably
40 µm to 500 µm, and more preferably 100 µm to 300 µm from the viewpoint of the effect
of the invention. The thickness, if less than 40 µm, lowers the film's gas barrier
effect, while if more than 500 µm, increases the throwing amount into the discard
in the dump to result in an increase in combustion heat in the incinerator.
[0033] The multilayer film in the invention is allowed to take various layer arrangements;
from the side in contact with photographic processing chemicals layers may be arranged,
for example, in various orders as described below:
(1) LLDPE/Ny(nylon)/PET(polyethylene terephthalate),
(2) LLDPE/Ny/EVOH(Eval)/Ny/ONy(orientated nylon),
(3) LLDPE/EVA(polyethylene-vinyl acetate copolymer)/Ny,
(4) LLDPE. S.PE (Sand polyethylene)/HDPE(high-density polyethylene,
(5) LLDPE/KON(vinylidene chloride-coated nylon),
(6) LLDPE/GLPET(ceramic-coated polyethylene terephthalate),
(7) PE(polyethylene)/EVOH/OPP(orientated polypropylene),
(8) LDPE(low-density polyethylene),
(9) LDPE/EVOH/ONy,
(10) PE/KPE(vinylidene chloride polyester),
(11) PE/Ny,
(12) PE/EVOH/Ny,
(13) PE/EVOH/KPE,
(14) PE/EVOH/KPET(vinylidene chloride-coated PET),
(15) LDPE/EVOH/KPET,
(16) EVA(polyethylene-vinyl acetate copolymer)/Ny,
(17) EVA/ONy,
(18) EVA/EVOH/ONy,
(19) LDPE/AN(Acrylonitrile)/Ny,
(20) LLDPE/S.PE/LLDPE/Ny/EVOH/Ny/ONy,
(21) LLDPE/S.PE/HDPE/S.PE/LLDPE/Ny/EVOH/Ny/PET,
(22) LLDPE/S.PE/LLDPE/Ny/EVOH/Ny/ONy, and
(23) LLDPE/S.PE/LLDPE/Ny/EVOH/Ny/PET.
[0034] Production of the multilayer film may be carried out with no restrictions in various
methods such as of film-to-film sticking together with an adhesive, film-to-film sticking
together with a molten resin, laminating two or more different resins extruded from
slits or other prevalent film laminating methods. These methods may be used alone
or in combination.
[0035] The silver halide photographic light-sensitive material processing chemicals packaging
material of the invention is preferably in the standing pouch form, an example of
which is shown in Figures 1 and 2. The packaging material is composed of a multilayer
film, the number of laminated layers of which is not limited.
[0036] In the figures, 1 is the pouch body, and 2 is its bottom. Each section is made of
a multilayer film.
[0037] The capacity of the pouch is preferably not more than 3 liters, and more preferably
not more than 2 liters for ease of handling. It is preferable for the pouch to be
provided with a catch or stopper in order to make it easier to handle.
[0038] The processing chemicals packaging material of the invention may be formed by, e.g.,
heat sealing the side and the upper part of body 1 and in the lower part also heat
sealing body 1 and bottom 1, but for the heating sealing section in the upper part
there are various embodiments as shown in Figures 3 and 4, wherein 3 is a heat sealing
section, L is a cutting line. By doing this, various embodiments can be obtained at
the take-out opening for the processing solution.
[0039] The packaging material of the invention can be used as containers for photographic
processing chemicals including those for use in processing all silver halide photographic
light-sensitive materials such as color films, color photographic papers, reversal
films, black-and-white films for general use, X-ray films, lith films for graphic
arts use, and micrographic films.
[0040] The photographic processing chemicals used in the invention are explained.
[0041] The photographic processing chemicals include a color developer, bleacher, fixer,
bleach-fixer, stabilizer, neutralizer, black-and-white developer, conditioner, stop-fixers,
and short stop.
[0042] Where the processing chemicals kit used in the invention is a bleacher kit or a bleach-fix
kit, the kit is characterized by having at least a compound represented by the foregoing
Formula B.
[0043] Acetic acid is conventionally used as an essential constituent of the bleaching or
bleach-fix solution for use in processing color photographic light-sensitive materials
or of the fixing solution for black-and-white films for general use, X-ray films and
lith films for graphic arts use. The use of an acetic acid-free bleaching or bleach-fix
solution in processing color photographic light-sensitive materials causes bleaching
fog or silver retention, thus adversely affecting photographic characteristics. The
acetic acid contained in the fixing solution in processing black-and-white films for
general use or X-ray films is indispensable to hardening such films.
[0044] The light-sensitive materials processing chemicals kit can be divided into some parts,
acetic acid in one part of which is more concentrated than the other chemicals parts.
Accordingly, the influence by the acid upon its packaging material is significant.
[0045] In order to reduce the degradation of the packaging material to improve the preservability
of processing solutions to thereby improve photographic characteristics, we, the inventors,
have made our continued investigations. As a result, to our surprise it has now been
found that the filling of a processing solution containing at least one of those compounds
represented by Formula B in a kit packaging material prevents the packaging material
from degradation.
[0046] The compound of Formula B is explained.
[0047] In Formula B, X₂ represents a hydroxyl group, a halogen atom, an amino group or a
-COOM³; A represents a saturated or unsaturated alkylene group which may have a substituent,
wherein M³ is a hydrogen atom, an ammonium group, an alkali metallic atom or an organic
ammonium group such as triethanol-ammonium.
[0048] In the invention, a processing solution containing at least one compound represented
by the foregoing Formula B is filled in a flexible packaging material having an oxygen
transmittance of preferably not more than 5.0cc/24hrs.atm, more preferably 2.0cc/24hrs.atm,
and most preferably 1.0cc/24hrs.atm under conditions of 30°C/70%RH, wherein the oxygen
transmittance is measured with an oxygen transmittance tester, manufactured by Oxtrancommon
Corp.
[0049] The following are useful examples of the compound represented by Formula B.
Exemplified Compounds:
[0050]
( B - 1 ) HOOCCH₂C(OH)(COOH)CH₂COOH
( B - 2 ) HOOC(CHOH)₂COOH
( B - 3 ) HOOCCH₂COOH
( B - 4 ) HOOCCH(OH)CH₂COOH
( B - 5 ) HOOCCH = CHCOOH
( B - 6 ) HOOCCH₂CH₂COOH
(B - 10) NaOOCCH = CHCOONa
(B - 11) KOOCCH = CHCOOK
(B - 12) H₄NOOCCH = CHCOONH₄
( B - 19) HOOCCH₂CH(CH₃)COOH
( B - 20) HOCH₂COOH
( B - 21) ClCH₂COOH
( B - 22) NH₂CH₂COOH
[0051] The preferred among the above exemplified compounds are the aliphatic dicarboxylic
acids B-2 to B-7, B-10 to B-12 and B-16 to B-19, and the most preferred are B-5, B-6
and B-16.
[0052] The adding amount of the compound of Formula B is preferably 0.05 to 2.0 mols, more
preferably 0.2 to 1.0 mol per liter of a bleaching or bleach-fix solution, [0039]
while in the case of a concentrated solution thereof, preferably 0.2 to 4.0 mols,
and most preferably 0.4 to 2.5 mols per liter.
[0053] Subsequently, the bleaching solution and bleach-fix solution are explained. The bleaching
agent to be used in the bleaching or bleach-fix solution is not restricted, but is
preferably a ferric complex salt of an organic acid represented by the following Formula
A or B or a ferric complex salt of diethylenetriaminepentaacetic acid.

wherein A₁ to A₄ may be either the same as or different from one another and each
represent -CH₂OH, -COOM or -PO₃M₁M₂, wherein M, M₁ and M₂ each respresent a hydrogen
atom, a sodium atom, a potassium atom or an ammonium group; and X is a substituted
or unsubstituted alkylene group having 2 to 6 carbon atoms.

wherein A₁, A₂, A₃ and A₄ may be either the same as or different from one another
and each represent a hydrogen atom, a hydroxyl group, -COOM, -PO₃M₂, -CH₂OH or a lower
alkyl group (methyl, isopropyl, n-propyl, etc.), provided at least one of A₁, A₂,
A₃ and A₄ is -COOM or -PO₃M₂; and [0045] M, M₁ and M₂ each represent a hydrogen atom,
an ammonium group, a sodium atom, a potassium atom, a lithium atom or an organic ammonium
group (e.g., trimethyl ammonium, triethanol ammonium, etc.).
[0054] The following are preferred examples of the compound represented by Formulas A and
B:
Exemplified Compounds:
[0056] In addition to these compounds A-1 through A-13, sodium salts, potassium salts or
ammonium salts of them may be suitably used as well.
[0057] From the viewpoint of the effect of the invention as well as the solubility, ferric-ammonium
salts of the above compounds may be preferably used.
[0058] In the invention, the preferably usable among the above compounds are A-1, A-4, A-7,
A-9 and A-13, and most preferably A-1 and A-9.
[0059] The concentration of the organic acid ferric complex salt contained in the processing
chemicals concentrated solution composition according to the invention is preferably
not less than 0.3 mol, more preferably 0.35 to 2 mols and most preferably 0.4 to 1
mol per liter of the composition.
[0060] The bleaching solution kit or bleach-fix solution kit of the invention may have both
the above organic ferric complex salt and a compound of Formula B contained in one
and the same part of the kit.
[0061] The bleaching solution or bleach-fix solution of the invention is used at a temperature
of preferably 20°C to 50°C, and more preferably 25°C to 45°C.
[0062] The bleaching solution or bleach-fix solution of the invention has a pH of preferably
not more than 5.0, and more preferably 2.0 to 4.7. Generally speaking, as pH becomes
lowered, the bleaching power increases, but it causes a leuco dye problem to tend
to occur. The problem, however, can be solved by combining the pH control with the
use of the invention's compound and an organic ferric complex salt, particularly,
ferric complex salts of organic acids represented by Formulas A and B.
[0063] The pH of the bleaching solution and/or bleach-fix solution of the invention is the
pH of the processing bath used when processing a silver halide light-sensitive material,
and is clearly distinguished from the pH of the so-called replenisher.
[0064] A silver halide such as ammonium bromide is normally added to the bleaching solution
and bleach-fix solution of the invention. The bleaching solution and bleach-fix solution
may also contain a brightening agent, defoaming agent or surfactant.
[0065] The preferred amount of the replenishisher to the bleaching solution is 20 to 500
ml, preferably 30 to 350 ml, more preferably 40 to 300 ml, and most preferably 50
to 250 ml per m² of a silver halide color photographic light-sensitive material. The
smaller the replenishing amount, the more conspicuous the effect of the invention
becomes.
[0066] The processing chemicals kit form is usually comprised of a fixer part and a bleaching
solution part, but may be partitioned into more parts.
[0067] The compound of Formula B of the invention preferably either is put in the bleaching
solution's part or forms an independent part of its own.
[0068] In the invention, in order to highly activate the bleaching solution or bleach-fix
solution, air or oxygen may, if necessary, be blown into its bath or its replenisher
tank, or else an appropriate oxidizing agent such as hydrogen peroxide, a bromate
or a persulfate may be discretionally added thereto.
[0069] In the invention, even if the accumulated silver and iodide amounts increase in the
fixing solution (e.g., up to Ag⁺6g or more/liter, up to I⁻0.6g or more/liter), the
objects of the invention can be accomplished without deteriorating the bleachability.
[0070] The bleach-fix solution of the invention, when its replenishing amount is not more
than 1200 ml per m² of a light-sensitive material, well exhibits the effect of the
invention. The replenishing amount is preferably 20 ml to 1000 ml, and more preferably
500 ml to 800 ml per m² of a light-sensitive material.
[0071] The total processing time of the bleaching solution and bleach-fix solution of the
invention is preferably not longer than 3 minutes and 45 seconds, more preferably
20 seconds to 3 minutes and 20 seconds, still more preferably 40 seconds to 3 minutes,
and most preferably 60 seconds to 2 minutes and 40 seconds.
[0072] The bleaching time may be discretionarily selected within the above total time limits,
but is preferably not longer than 1 minute and 30 seconds, particularly 10 seconds
to 70 seconds and most preferably 20 seconds to 55 seconds.
[0073] The bleach-fix solution's processing time may be arbitrarily selected within the
above total time range, but is preferably not more than 3 minutes and 10 seconds,
more preferably 10 seconds to 2 minutes and 40 seconds, and most preferably 20 seconds
to 2 minutes and 10 seconds.
[0074] In the processing method of the invention, it is preferable as an embodiment of the
invention to apply a forced stirring to the bleaching solution and bleach-fix solution
because the use of a forced stirring is suitable not only for raising the effect of
the invention but also for rapid processing. The forced stirring herein is not the
usual diffusion transfer of a liquid but implies that a liquid is forcibly stirred
by the application of a stirring means.
[0075] As the forcibly stirring means there may be used the means described in Japanese
Patent Application No. 48930/1988.
[0076] Suitable examples of the procedure steps in the processing method of the invention
are given below:
(1) Color developing → bleaching → fixing → washing,
(2) Color developing → bleaching → fixing → washing → stabilizing,
(3) Color developing → bleaching → fixing → stabilizing,
(4) Color developing → bleaching → fixing → 1st stabilizing → 2nd stabilizing,
(5) Color developing → bleaching → bleach-fix → washing,
(6) Color developing → bleaching → bleach-fix → washing → stabilizing,
(7) Color developing → bleaching → bleach-fix → stabilizing,
(8) Color developing → bleaching → bleach-fix → 1st stabilizing → 2nd stabilizing,
(9) Color developing → bleach-fix → fixing → stabilizing,
(10) Color developing → bleach-fix → washing,
(11) Color developing → bleach-fix → stabilizing.
[0077] The preferred among the above processing procedures listed in above are (3), (4),
(7) and (8), and the more preferred are (3) and (4).
[0078] Where the processing kit used in the invention is a color developer replenisher kit,
it is characterized by containing at least one compound represented by Formula 1.
[0079] The compound of Formula 1 is explained.
[0080] In Formula 1, L represents a straight-chain or branched-chain substitutable alkylene
group having preferably 1 to 10 carbon atoms and more preferably 1 to 5 carbon atoms,
such as methylene, ethylene, trimethylene and propylene, wherein the substituent includes
carboxy, sulfo, phosphono, phosphinic acid residue, hydroxy and alkyl-substitutable
ammonia groups, the preferred ones out of which groups are the carboxy, sulfo, phosphono
and hydroxy groups. A represents a carboxy group, a sulfo group, a phosphono group,
a phosphinic acid residue, a hydroxy group, an alkyl-substitutable amino group, an

examples of the -L-A includes carboxymethyl, carboxyethyl, carboxypropyl, sulfoethyl,
sulfopropyl, sulfobutyl, phosphonomethyl, phosphonoethyl and hydroxyethyl groups,
the most preferred ones out of which groups are the carboxymethyl, carboxyethyl, sulfoethyl,

ammonium, alkyl-substitutable carbamoyl, alkyl-substitutable sulfamoyl, substitutable
alkylsulfonyl, acylamino, alkylsulfonyl, acylamino, alkylsulfonylamino, arylsulfonylamino,
alkoxycarbonyl, alkyl-substitutable amino, arylsulfonyl, nitro, and cyano groups and
halogen atoms. R may have two or more of the above substituents. Useful examples of
R include a hydrogen atom and methyl, ethyl, propyl, carboxymethyl, carboxyethyl,
carboxypropyl, sulfoethyl, sulfopropyl, sulfobutyl, phosphonomethyl, phosphonoethyl
and hydroxyethyl groups. Out of these groups the most preferred are the hydrogen atom,
carboxymethyl, carboxyethyl, sulfoethyl, sulfopropyl, phosphonomethyl and phosphonoethyl
group. L and R may link to form a ring.
[0082] The preferred among the above listed compounds are (2), (7), (14), (38), (39), (40)
and (55).
[0083] The compound of Formula 1 can be synthesized by the alkylation reaction (nucleophilic
substitution reaction, addition reaction, Mannich reaction) of a commercially available
hydroxylamine product. The synthesis may be carried out by making reference to the
synthesis methods described in West German Patent No. 1,159,634 and the Inorganica
Chemica Acta, 93, (1984) 101-108.
[0084] Some of the above compounds of Formula 1 are described in JP O.P.I. No. 264751/1988,
so that they are known as preservatives for a color developer solution. However, the
object of the invention is to improve the durability of a flexible packaging material
filled with a processing solution containing a preservative as well as to improve
the processing solution's stability against chang in concentration of the preservative,
and the above publication makes no mention of these points at all. A large improvement
on the durability of the flexible container in the case of using the compound of Formula
1 is a brand-new technique, showing a surprising effect.
[0085] In the invention, where a color developer is provided in a product form of kit chemicals,
the kit is preferably available in a pack partitioned into 2 to 4 parts. A kit of
five or more parts is undesirable because it makes its preparation work complicated,
increasing the possibility of misdisolving.
[0086] In the invention, (1) a color developing agnet and (2) an alkali agent-containing
high pH solution are desirable to be packed in separate parts. In this instance, the
compound of Formula 1 may be contained in either (1) or (2), but is more preferably
contained in another, a third part.
[0087] The third part, containing the compound of Formula 1, may additionally contain a
glycol compound such as ethylene glycol, diethylene glycol or polyethylene glycol;
an alkanolamine such as diethanolamine or triethanolamine; a chelating agent such
as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic acid or 1-hydroxyethylidene-1,1-diphosphonic
acid; an aromatic carboxylic acid such as paratoluenesulfonic acid; an alkali halide,
a surfactant, a brightening agent, and the like.
[0088] The color developing agent used in the color developer of the invention is preferably
a p-phenylenediamine compound having a hydrophilic group. This compound is suitably
used since it satisfactorily effectuates the object of the invention and little produces
fog in processing.
[0089] The p-phenylenediamine compound having a hydrophilic group have the advantage that
it less stains a light-sensitive material in processing and, when attached to the
skin, less develops skin rash than does a hydrophilic group-free p-phenylenediamine
compound such as N,N-diethyl-p-phenylenediamine.
[0090] Regarding the foregoing hydrophilic group, there are p-phenylenediamine compounds
having at least one hydrophilic group on the amino group thereof or on the benzene
ring thereof. Particular examples of the hydrophilic group include:

wherein m and n each are an integer of zero, 1 or more; -COOH and -SO₃H.
[0091] Suitably usable examples of the color developing agent in the invention include Compounds
C-1 to C-16 described in Japanese Patent Application No. 203169/1990, pp.26-31; Compounds
1 to 8 described in JP O.P.I. No. 289350/1986, pp.29-31; and Compounds 1 to 62 described
in JP O.P.I. No. 246543/1991, pp.5-9. Of these compounds the most preferred are the
Compounds C-1 and C-3 in Japanese Patent Application No. 203169/1990, the Compound
2 in JP O.P.I. No. 289350/1986 and the Compound 1 in JP O.P.I. No. 246543/1991.
[0092] The above color developing agent is used usually in the form of a salt such as a
hydrochloride, sulfate or p-toluene-sulfonate.
[0093] The using amount of the color developing agent is preferably not less than 0.5x10⁻²
mol, more preferably 1.0x10⁻² to 1.0x10⁻¹ mol, and most preferably 1.5x10⁻² to 1.0x10⁻¹
mol per liter of a color developer solution.
[0094] The compound represented by Formula 1 is contained in a concentration of preferably
1.5x10⁻³ to 1.5x10⁻¹ mol, and more preferably 5.0x10⁻³ to 1.0x10⁻¹ mol per liter of
a color developer tank solution. As a preservative a sulfate may be used in combination
with the compound.
[0095] A development accelerator may, if necessary, be added to the color developer solution.
Examples of the development accelerator include the thioether compounds described
in JP E.P. Nos. 16088/1962, 5987/1962, 7826/1963, 12380/1969 and 9019/1970, and U.S.
Patent No. 3,813,247; the p-phenylenediamine compounds described in JP O.P.I. Nos.
49829/1977 and 15554/1975; the quaternary ammonium salts described in JP O.P.I. No.
137726/1975, JP E.P. No. 30074/1969, JP O.P.I. Nos. 156826/1981 and 43429/1977; the
p-aminophenols described in U.S. Patent Nos. 2,610,122 and 4,119,462; the amine compounds
described in U.S. Patent Nos. 2,494,903, 3,128,182, 4,230,796, 3,253,919, 2,482,546,
2,596,926 and 3,582,346, and JP E.P. No. 11431/1966; the polyalkylene oxides described
in JP E.P. Nos. 16088/1962, 11431/1966, 23883/1967 and 25201/1967, and U.S. Patent
Nos. 3,128,183 and 3,532,501; and further, 1-phenyl-3-pyrazolidones, hydrazines, mesoionic-type
compounds, ionic-type compounds and imidazoles.
[0096] The color developer solution is preferably one substantially not containing benzyl
alcohol, wherein the '...substantially not containing ...' means that the color developer
tank solution contains benzyl alcohol in preferably 2.0 ml or less/liter, and more
preferably contains no benzyl alcohol at all. The color developer solution, when substantially
not containing benzyl alcohol, less changes photographic characteristics and less
increases stain in running processing than when containing, and further causes no
delamination of the film container, thus providing better results.
[0097] It is preferable for the color developer tank solution to contain chlorine and bromine
ions for the antifogging purpose. The chlorin ion content is preferably 1.0x10⁻² to
1.5x10⁻¹ mol/litter, and more preferably 4x10⁻² to 1x10⁻¹ mol/liter. The chlorine
ion concentration, when higher than 1.5x10⁻¹mol/liter, retards the developing rate,
so that it is undesirable for obtaining the maximum density rapidly, while when lower
than 1.0x10⁻² mol/liter, produces stain and further increases the variation of photographic
characteristics (particularly the minimum density) due to running processing.
[0098] The bromine ion concentration is preferably 3.0x10⁻⁵ to 1x10⁻³ mol/liter, and more
preferably 5.0x10⁻⁵ to 5.0x10⁻⁴mol/liter. The bromine ion concentration, when not
less than 1x10⁻³ mol/liter, retards the developing rate and lowers the maximum density
and sensitivity, while when lower than 3.0x10⁻⁵ mol/liter, produces stain and increases
the variation of photographic characteristics (particularly the minimum density) due
to running processing.
[0099] The color developer solution used in the invention may, if necessary, contain chlorine
and bromine ions by adding an arbitrary antifoggant thereto. As the antifoggant there
may be used an alkali metal halide, such as potassium iodide, and organic antifogging
agents. Examples of the organic antifogging agent include nitrogen-containing heterocyclic
compounds such as benzotriazole, 6-nitrobenzimidazole, 5-nitroisoindazole, 5-methylbenzotriazole,
5-nitrobenzotriazole, 5-chlorobenzotriazole, 2-thiazolyl-benzimidazole, 2-thiazolylmethylbenzimidazole,
indazole, hydroxyazaindolidine, adenine and 6-benzyladenine.
[0100] Incorporation of a triazinylstilbene brightening agent into the color developer solution
of the invention is preferable from the effect of the invention point of view.
[0101] The suitable as the brightening agent are triazinylstilbene compounds, especially
those represented by the following Formula 2:

[0102] Formula 2 is as defined for the Formula E described in Japanese Patent Application
No. 178833/1990, pp.73-75.
[0103] Exemplified Compounds 2-1 to 2-45 for Formula 2 are the same as those of E-1 to E-45
shown in Japanese Patent Application No. 178833/1990, pp.76-82.
[0104] The triazinylstilbene brightening agent is commercially available, but can be synthesized
in the usual manner as described in the 'Keikozohakuzai,' ('Brightening Agents') compiled
by Kaseihin Kogyo Kai (Chemical Industries Association) (published in Aug. 1976).
[0105] Among the exemplified compounds those most suitably usable are 2-4, 2-24, 2-34, 2-35,
2-36, 2-37 and 2-41.
[0106] The triazinylstilbene brightening agent content of the color developer tank solution
is preferably in the range of 0.2 to 10g, and more preferably 0.4 to 5g per liter
thereof.
[0107] In addition, various other additives may be used such as antistain agents, antisludge
agents, intereffect acceleration agents, and the like.
[0108] Further, the incorporation into the color developer solution of any one of those
chelating agents represented by the following Formula K and its exemplifed Compounds
K-1 to K-22 which are described in Japanese Patent Publication No. 240400/1990 is
preferred from the viewpoint of effectuating the object of the invention.

[0109] The preferred among these chelating agents are K-2, K-9, K-12, K-13, K-17 and K-19,
and especially the addition of K-2 and K-9 satisfactorily exhibits the effect of the
invention.
[0110] The adding amount of the chelating agent is preferably 0.1 to 20g, and more preferably
0.2 to 8g per liter of the color developer tank solution.
[0111] In the invention, the above color developer solution may be used at an arbitrary
pH value, but is used preferably at pH 9.5 to 13.0, and more preferably pH 9.8 to
12.0 from the rapid processing point of view. The processing temperature of the color
developer solution is normally not less than 30°C, preferably not less than 33°C,
and most preferably 35 to 65°C. The processing time is preferably within 90 seconds,
more preferably not less than 3 seconds and less than 60 seconds, and most preferably
3 seconds to 45 seconds.
[0112] In the processing method of the invention, the processing steps and solutions other
than the processing using the above color developer solution employ known processing
steps and solutions.
[0113] As the fixing agent used in the fixer kit of the invention a thiosulfate or a thiocyanate
is used. The thiocyanate content of the fixer solution is preferably at least not
less than 0.1 mol/liter, and when processing color negative film, more preferably
not less than 0.5 mol/liter, and most preferably not less than 1.0 mol/liter. The
thiosulfate content of the fixer solution is preferably at least not less than 0.2
mol/liter, and when processing color negative film, more preferably not less than
0.5 mol/liter. The object of the invention can be more effectively accomplished by
using a thiosulfate in combination with a thiocyanate.
[0114] The photographic processing kit having a fixability in the invention may contain
one or two or more kinds of pH buffer comprising various salts in addition to the
above fixing agents. Further, it is preferable for the kit to contain a large amount
of an alkali halide or ammonium halide as a rehalogenating agent, such as potassium
bromide, sodium bromide, sodium chloride, ammonium bromide, etc. Further, those additives
known to be usually added to a fixing or bleaching bath, such as alkylamines, polyethylene
oxides, and the like, may also be arbitrarily added to the kit.
[0115] In the invention, the ammonium cation's proportion to the total cations in the thiosulfate-containing
fixer solution was varied.
[0116] The ammonium cation concentration proportion to the whole cations in the fixer is
preferably 50 to 0 mol%, more preferably 20 to 0 mol%, and most preferably 10 to 0
mol%.
[0117] To the photographic processing kit having fixability of the invention is preferably
added any one of those compounds represented by the Formula FA and its exemplified
Compounds FA-1 to FA-39 or of those compounds of the Formula FB described in Japanese
Patent Application No. 206120/1990. The addition of it can better exhibit the effect
of the invention and can also provide a supplemental effect that it produces little
or no sludge in a fixability-having processing solution used for processing small
quantities of light-sensitive materials over an extensive period.

wherein R' and R'' each represent a hydrogen atom, an alkyl group, an aryl group,
an aralkyl group or a nitrogen-containing heterocyclic group; and n is an integer
of 2 or 3.
[0119] These compounds of Formula FA can be synthesized in accordance with those prevalent
methods as described in U.S. Patent Nos. 3,335,161 and 3,260,718.
[0120] The group of Compounds FB are as follows:
FB-1: Thiourea
FB-2: Thiocyano catechol
[0121] The above compounds represented by Formula FA and the group of Compounds FB may be
used alone or in combination of two or more kinds thereof; for example, FB-1 and FA-21,
FB-1 and FA-12, FA-12 and FA-38, FA-12 and FA-32, FA-12 and FA-21. The most preferred
is FB-1.
[0122] The adding amount of these compounds of Formula FA and the group of Compounds FB
is in the range of preferably 0.1 to 300g, more preferably 0.2 to 200g and most preferably
0.5 to 150g per liter of the processing solution.
[0123] Subsequently, the stabilizer is explained. The stabilizer contains preferably a chelating
agent whose chelate stability constant to ferric ions is not less than 8, wherein
the chelate stability constant implies the constant generally known by L. G. Sillen
and A. E. Martell, the 'Stability Constants of Metal-ion Complexes,' The Chemical
Society, London (1964), and S. Chaberek and A.E. Martell, the 'Organic Sequestering
Agents,' Wiley (1959).
[0124] Examples of the chelating agent whose chelate stability constant to ferric ions is
not less than 8 in clude those as described in Japanese Patent Application Nos. 234776/1990
and 324507/1989.
[0125] The using amount of the above chelating agent is preferably 0.01 to 50g, and more
preferably 0.05 to 20g per liter of the stabilizer tank solution.
[0126] Useful compounds as the additive to the stabilizer kit include ammonium compounds,
which can be provided by ammonium salts of various inorganic compounds. The adding
amount of the ammonium compound is preferably 0.001 mol to 1.0 mol, and more preferably
0.002 to 2.0 mol per mol of the stabilizer tank solution.
[0127] Further, the stabilizer preferably contains a sulfite, and also contains a surfactant.
Examples of the surfactant include those water-soluble organic siloxane compounds
represented by the Formula II described in p.6 of Japanese Patent Application No.
274026/1990 and its exemplified Compounds II-1 to II-17 described in pp.67-70 of the
same publication. The preferred among the exemplified compounds are Compounds II-1,
II-3, II-7, II-13, II-15, II-16 and II-17. Alternatively, those compounds represented
by the Formulas I and II described in JP O.P.I. No. 250449/1987 may be used. For the
adding amount of them reference can be made to the same publication.
[0128] It is preferable for the stabilizer to contain a metallic salt in combination with
the above-mentioned chelating agent. The metallic salt can be provided in the form
of an inorganic salt such as the halide, hydroxide, sulfate, carbonate, phosphate
or acetate of such a metal as Ba, Ca, Ce, Co, In, La, Mn, Ni, Bi, Pb, Sn, Zn, Ti,

[0131] The present invention is illustrated further in detail by the following examples.
EXAMPLE 1
[0132] The following parts of a color developer replenisher kit (10-liter kit) for processing

[0136] Each prepared kit packed in a corrugated cardboard box was set in an oscillation
tester to be subjected to 24-hour oscillation treatment and then to aging treatment
under conditions of 50°C/15%RH in an autoclave over a period of 50 days.
[0137] The aged kit was used to prepare a color developer replenisher and starter solutions
for processing color photographic paper, and the solutions were loaded in a CL-PP1701
Printer-Processor, manufactured by KONICA Corp. In the printer-processor, a color
paper Type QA-A5, produced by KONICA Corp., was used and subjected to wedge exposure
in the usual manner and then to running processing. For the bleach-fix and stabilization
in the running processing, R-20P2R-01 and R-20P3R-01, produced by KONICA Corp., were

[0141] As is apparent from Table 2, the invention can provide a silver halide photographic
light-sensitive material processing chemicals kit packaging material which, even after
being aged, enables to obtain satisfactory photographic characteristics; produces
almost no crystal deposition on the autoprocessor's walls; generates little or no
harmful chlorine gas at the time of its incineration; and can be easily thrown into
the discard because of its collapsibility and its small weight.

[0142] Tests were made in the same manner as in Example 1 except that the thickness of the
LDPE and EVOH used in the flexible processing chemicals package material used in the
test No.5 in Example 1 was varied to prepare container samples having the following

[0155] As is apparent from Table 5, the packaging material of the invention is not degraded
nor stained during its storage. The replenisher prepared from the kit that has been
aged has an excellently stable pH value. As for the kit constitution, a plural parts
constitution is preferred to a single part constitution.
EXAMPLE 5
[0156] A concentrated bleaching solution of the following part constitution for color negatives
were prepared for 5 liters of a replenisher solution and filled in a container as
shown in Fig. 1 made of the packaging material given in Table 5, and the opening of
the container was heat-sealed, whereby a bleaching solution kit was prepared.

[0161] It is understood that the use of the packaging material having a steam transmittance
of not more than 10g/m².day is more preferable to lower the reduction rate of its
content.
EXAMPLE 7
Preparation of a silver halide photographic light-sensitive material (color photographic
paper)
[0162] A paper support laminated with polyethylene on one side thereof and with a titanium
oxide-containing polyethylene on the other side thereof was used to coat on the titanium
oxide-containing polyethylene-laminated side the following component layers in the
described order from the support, whereby a multilayer silver halide color photographic
light-sensitive material was prepared.

[0163] The coating liquid for the above layers were prepared as follows:
Layer 1 coating liquid:
[0164] A solution of 26.7g of yellow coupler Y-1, 100g of dye image stabilizer ST-1. 6.67g
of ST-2 and 0.67g of additive HQ-1 dissolved in 6.67g of high-boiling solvent DNP
with 60cc of ethyl acetate was emulsifiedly dispersed by means of a supersonic homogenizer
into 220cc of aqueous 10% gelatin solution containing 7cc of 20% surfactant SU-1 to
thereby prepare a yellow coupler dispersion. This dispersion was mixed with a blue-sensitive
silver halide emulsion (containing 10g of silver) that was prepared in the following
manner, whereby a Layer-1 coating liquid was obtained.
[0165] Layer-2 to Layer-7 coating liquids also were prepared in similar manner to the above
Layer-1 coating liquid.
[0166] Hardening agent H-1 was added to Layer-2 and Layer-4, and H-2 to Layer-7. As the
coating aid surfactants SU-2 and SU-3 were added to the above liquids for their surface
tension adjustment.
Preparation of a blue-sensitive silver halide emulsion
[0168] To 1000 cc of an aqueous 2% gelatin solution kept at 40°C the following Solutions
A and B were added simultaneously with pAg and pH controlled to 6.5 and 3.0, respectively,
spending 30 minutes, and further the following Solutions C and D simultaneously with
pAg and pH controlled to 7.3 and 5.5, respectively, spending 180 minutes.
[0169] In this instance, the pAg control was made according to the method described in JP
O.P.I. No.45437/1984, while the pH control was made with use of an aqueous solution
of sulfuric acid or sodium hydroxide.

[0174] After completion of the addition, the emulsion was desalted by using an aqueous 5%
solution of Demol N, produced by Kawo Atlas Co., and an aqueous 20% magnesium sulfate
solution, and then mixed with an aqueous gelatin solution, whereby a mono-disperse
cubic emulsion EM P-1, having an average grain size of 0.85µm, a grain size distribution
with a coefficient of variation of 7% and a silver chloride content of 99.5 mol% was
obtained.
[0175] The above emulsion EMP-1 was subjected to a 90-minute chemical ripening treatment
at 50°C with use of the following compounds, whereby a blue-sensitive silver halide
emulsion Em-A was obtained.

[0176] A monodisperse cubic emulsion EMP-2, having an average grain size of 0.43µm, a grain
size distribution with a coefficient of variation of 8% and a silver chloride content
of 99.5 mol%, was prepared in the same manner as in EMP-1 except that the adding time
of Solutions A and B and that of Solutions C and D were changed.
[0177] The emulsion EMP-2 was subjected to a 120-minute chemical ripening treatment at 55°C
with use of the following compounds, whereby a green-sensitive silver halide emulsion

[0190] The color photographic paper, developer and developer replenisher that were prepared
earlier, were used along with the above prepared bleach-fix, stabilizer and their
replenishers to make running processing.
[0191] The running processing was made in the manner that the color photographic paper was
continually processed by an automatic processor with its respective tanks filled with
the foregoing color developer, bleach-fix and stabilizer solutions while being replenished
by supplying through metering pumps the above color developer replenisher, bleach-fix
replenisher and stabilizer replenisher, respectively.
[0192] The running processing was lasted until the time when the amount of the bleach-fix
replenisher supplied to the bleach-fix tank solution comes to three times the capacity
of the bleach-fix solution tank.
[0193] After the processing, the color paper was divided into two, of which one was exposed
to fluorescent X-rays to examine the residual silver amount in its exposed area, while
the other was examined with respect to the yellow density in its unexposed area.

[0206] As is apparent from Tables 16 to 18, the combined use of the container and the compound
of the invention causes little degradation of the joint section and almost no deterioration
of the strength of the container even after its storage at a high temperature; particularly
no degradation of the joint section was found at all in the oxygen transmittance of
not more than 2.0cc/m².day.atm. and no deterioration of the strength was found at
all in the oxygen transmittance of not more than 1.0cc/m².day.atm.
EXAMPLE 10
[0207] Of the Test No. 1-42 container in Example 9, the thicknesses of its LDPE and EVOH
alone were changed to prepare containers having the steam transmittance values shown
in the following Table 19, and they were evaluated in the same manner as in Example
8. The results are shown in Table 19.

[0208] From Table 19 it is apparent that in the case of the steam transmittance of not more
than 10g/m².day, no degradation of the joint section is found at all, while in the
case of not more than 5g/m².day, no deterioration of the strength occurs at all.

[0211] To make a replenisher solution, the above parts A, B and C are added in the described
order to be dissolved with stirring in 8.6 liters of water, and finally water is added
again to make the whole 10 liters.
[0212] To make a starter solution, to the replenisher in an amount 70% of that of a starter
solution-to-be are added 0.015g of potassium bromide, 2.3g of potassium chloride and
2.5g of 50% sulfuric acid per liter thereof, and finally water is added to make the
whole 100%.
[0213] Two kits of the above parts A, B and C were prepared, and one kit was stored at a
temperature of 10°C, while the other was stored over a period of 3 weeks at a temperature
of 50°C.
[0214] The stored kits were used to prepare two different color developer replenisher solutions
for color paper, and from the kit that was stored at a lower temperature a starter
was prepared. These were put in a CL-PP1701 printer/processor with a modified color
developing bath, manufactured by KONICA Corp., to make running processing of Color
Paper type QA-A5, produced by KONICA Corp., that was exposed through a wedge in the
usual manner. In the running processing the bleach-fix and stabilizer solutions used
are K-20P2R-01 and K-20P3R-01, produced by KONICA Corp. The two different color replenisher
solutions were alternated with each other every 0.5R, and running processing for 0.05R
per day was lasted until the amount of the replenished solution comes to 2.5 times
the the color developer tank capacity, wherein the term 1 R implies that the color
developer replenisher solution in a quantity corresponding to the color developer
tank capacity is totally supplied for replenishment.

[0217] From Table 20 it is understood that the combined use of the container and the preservative
of the invention causes little or no deterioration or change in the color density
and retains an always stable processability. Namely, the invention enables the obtaining
of an always constant processability regardless of storing conditions of the kit chemicals.
EXAMPLE 12

[0221] To make a replenisher solution, the above parts A, B and C are added in the described
order to be dissolved in 8 liters of water, and further water is added to make the
whole 10 liters.
[0222] To make a starter solution, to the replenisher solution in an amount 76% of that
of a starter solution-to-be are added 0.9g of potassium bromide and 0.6mg of potassium
iodide per liter thereof, and pH of it is adjusted to 10.01.
[0223] Two kits of the above parts were prepared; one kit was stored at a temperature of
10°C, while the other at a temperature of 50°C for three weeks.
[0224] The stored kits were used to prepare two different color developer replenishers for
processing color negative films, and from the kit that was stored at a lower temperature
a starter solution was prepared. These were put in a CL-KP-50QA negative film processor,
manufactured by KONICA Corp., to make running processing of Color Negative Film Super
DD-100, produced by KONICA Corp., exposed through a wedge in the usual manner. In
the above running processing, the bleaching, fixing and stabilizing solutions used
are K-52N2R-01, K-52M3R-01 and K-52N4R-01, respectively. The two different color developer
replenisher solutions were alternated with each other every 0.5R, and the running
processing was made for 0.05R/day and lasted until the quantity of the replenished
liquid comes to 2.5 times the tank capacity.

salt) changed so as to obtain the ratio (mol%) of ammonium ions to the total cations
as shown in the following table.
[0230] Further, ammonia water or a sodium hydroxide solution was used to adjust pH to 7.0,
and water was added to make the whole one liter.
[0231] One liter of the above prepared solution was filled in each of the invention's flexible
containers (also called 'standing pouch' due to its form, abbreviated to SP. The standing
pouch's composition used in this test is comprised of PET12µ/Ny5µ/EVOH5µ/Ny5µ/LLDPE5µ/S.PE20µ/HDPE40µ/S.PE20µ/LLDPE-80µ;
the same shall apply hereinafter), a conventional plastic bottle (PB, made of LDPE
50µm), and a glass bottle (GB), and these were allowed to stand at 50°C over a period
of one month. After the one-month storage, the degrees of swelling of and of deposition
on the cap and inside wall of each container were examined visually. The results are
given below.
[0232] The symbols represent as follows:
- LDPE:
- Low-density polyethylene
- OPP:

[0233] The symbols used for evaluation define as follows:
Swelling degree of container
[0234]
A: Little or no swelling is found.
B: The container is found swollen, but still stretchable.
C: The container is swollen up to its limit and cannot stretch any longer.
Ease of opening
[0235]
A: The container can be easily opened in the usual manner with no gas leakage.
B: The container can be opened, but slight gas leakage occurs.
C: It is difficult to open the container with the possibility that its filled gas
could burst out to attack the operator.
[0236] It is apparent from the above results that the ratio of ammonium ions to the whole
cations in the invention, when not more than 50 mol%, brings good results, and when
not more than 20 mol%, brings better results to any of the testing items.
[0237] The similar results were obtained also when using ammonium and potassium ions, and
further even when using a mixture of ammonium, potassium and sodium ions as the cations.
[0238] Tests were made in like manner except that the standing pouch's layer composition
was replaced by the following one, and almost the same results were obtained.
Layer composition:
[0239] PET12µ/Ny5µ/EVOH5µ/Ny5µ/LLDPE25µ/S.PE20µ/LLDPE80µ
